Every four seconds someone is diagnosed with Alzheimer’s currently the disease affects over fourty million people worldwide. Dr Alois Alzheimer was a German psychiatrist who first described the symptoms of Alzheimer’s in 1901 when he noticed a particular hospital patient had peculiar problems which were a difficulty in sleeping‚ disturbed memories‚ drastic changes to mood throughout the day and general confusion. When the patient passed away Dr Alzheimer was able to conduct an autopsy on the body

Summary of The Cell Structure Bora Zivkovic introduces and describes the basic cell structure by using professional and academic language. First of all‚ she cites some comprehensible examples at the beginning of the article in order to explain that every cell has different size such as the largest animal cell - ostrich egg. She also emphasizes that it’s important to focus on the nuances. Then‚ she starts her main body. She introduces the basic structure of the cell from outer parts of the cell

Peroxisomes contain enzymes for detoxification. One of the enzymes within peroxisomes is catalase. Catalase is involved in the breakdown of hydrogen peroxide. Microfilaments are made of actin. They form the cells cytoskeleton. Centrioles are composed of microtubules. Centrioles are at the base of cilia and flagella. They are also involved with cell division. Ribosomes are assembled in the nucleoli. The nucleolus is a spherical area within the cell nucleus. 5. Which of the following is NOT considered an

Millions and millions of cells must be formed in order for an organism (whether a plant or animal) to be created. That becomes possible through cell division. Cell division happens when all of the DNA of a cell is replicated completely and then that complete replication (called a genome) is separated‚ breaking apart into two daughter cells that are identical to the original cell (Erster 3-4). There are different kinds of division depending on the type of cell involved (Erster 25). However‚ regardless

CELL STRUCTURE CELL THEORY: Structural and functional unit of all living things New cells arise from already existing cells Cells contain information that instructs growth. This information can be passed onto new cells. MICROSCOPES: There are two main types of microscopes: Light and Electron Electron Micrographs- shown in colour LIGHT ELECTRON Uses beam of light Magnification = x1500 Resolution = 200 nm Wide range of specimens can be used Samples are fairly quick + easy to prepare

Artificial Sweeteners 1. Artificial sweeteners are a sugar substance that is a food additive that duplicates the effect of sugar taste‚ usually with less food energy. 2. No‚ it is possible that these artificial sweeteners can change the way we taste food‚ over stimulation of sugar receptors from frequent use of these hyper-intense sweeteners may limit tolerance for more complex tastes. 3. No‚ food processors should be allowed to put them in food because they do not give much energy. Also‚ food

The three-domain system is a biological classification that divides cellular life forms into archaea‚ bacteria‚ and eukaryote domains. It emphasizes the separation of prokaryotes into two groups‚ called Bacteria and Archaea. These two groups and eukaryotes each came from separate ancestors with poorly developed genetic make-ups. This classification system recognizes the fundamental divide between the two prokaryotic groups. Archaea appear to be more closely related to eukaryotes than they are to
